Spatio-temporal dynamics in an array of time delayed Van der Pol oscillators

The spatio-temporal phenomena in coupled map lattices (CML) are investigated. We propose time delayed Van der Pol oscillator as a unit lattice of CML, which is described with discrete time. This is the first attempt to construct CML with realizable circuits, as far as we know. Clusterization and the ways of collapse of clusters to spatio-temporal chaos are observed in this system.
